Very unusual plant
Has anyone ever grown an Echium Pininana tree plant, as shown in the picture I have been growing this for five years or more. The first two years it was a mass of leaves about two feet high then following year one mighty stalk about 5feet with lovely pink flowers and the bees love it. Then as it was going over it produced three stalks from the main stem, now this year the three have grown and flowered beautifully but now going to seed. I'm wondering if i cut it down would it start a new shoot? The seeds take years to grow. Any advice is welcome.
